Most media stories set in shopping malls don't really tell you much about what it feels like for the people who work in a big retail operation, or for the people who hang out at the mall. Because the mall's more than just sales.

Yes, some stores are going out of business in the Cool Springs Galleria, but it's just two stores. We talk to staff at one store that’s closing down, and at another, in the food court, where business is great.

In a part of the mall no shoppers ever see, there's a snug, dark little room with 43 TV screens, one for each of the cameras in the hallways and parking lots, the roof and the loading dock. We hang out with the security people who work in there, seeing what they see.
